I noticed that when -mgeneral-regs-only FP registers are still used by the LRA for spilling. Though in rare cases I saw an ICE because of it, even when it works it seems to me that the compiler should follow the desires of its user.
If you've noticed that mgeneral-regs-only causes the use of FP registers that is a bug and needs to be fixed. Please file a proper bug report with an actual testcase that can be of use for someone to recreate the problem.
I filed PR 62014 and posted there a patch to address this issue and restrict the LRA from using FP registers if the user so desires.
Please send patches to the mailing list. I think however in this case you are papering over the problem as explained in the PR.
